In my React app I just want to make simple GET requests to the Browse API to show to users on my site. For the Oauth authorisation I am following the Client Credentials flow https://developer.ebay.com/api-docs/static/oauth-client-credentials-grant.html..
For testing purposes I am using cURL and I'm not seeing any mention of a refresh token in the response. Is that because the refresh token doesn't expire applications, and you only need to get a new refresh token (after 18 months) for authorisation code grant flow https://developer.ebay.com/api-docs/static/oauth-authorization-code-grant.html
If I'm mistaken, please let me know!
